Avril actually started feeling the symptoms of the sickness in Vegas where she was celebrating her 30th birthday with her friends last September.

The rocker chick opened up to People about that fateful day, saying:

"I could barely eat, and when we went to the pool, I had to leave and go lie in bed. My friends asked, 'What's wrong?' I didn't know."

A couple of months after that incident, the Canadian went to the doctors and was diagnosed with a severe case of Lyme disease.

Avril believes she was bitten by a tick sometime last spring and said:

"I had no idea a bug bite could do this. I was bedridden for five months. I felt like I couldn't breathe, I couldn't talk and I couldn't move. I thought I was dying. There were definitely times I couldn't shower for a full week because I could barely stand. It felt like having all your life sucked out of you."

Eep. That sounds really scary…

Since her prognosis, Av has been slowly getting better. Her family has been taking care of her in Ontario, Canada with her husband coming back home every so often to check in on her.
